DC-ATE,
Nitpicking, as is my wont, but most of your examples are not acronyms, just abbreviations (another old far. ... eh, fella, butting in).
"Acronym - An abbreviation formed by (usually initial) letters taken from a word or series of words, and which is itself pronounced as a word, such as RAM" was the neatest definition I found.
The criterium is that it has to be "pronounceable", and is used as such.
So 'EICAS' and 'FADEC' qualify, 'PFD' doesn't.
'ADI' (attitude director indicator) doesn't qualify either, because it's never pronounced "aadie" but always "aa-die-eye".
I always like it when people come up with good catchy acronyms.
Exmek,
Thanks for the link to the Airbus batch.
Amusing to see they left out the infamous IFE (after the A380 debacle, no doubt).
